0 Preheat the oven to 350 degrees F / 180 C. Line a loaf pan with parchment paper.
1 Mix the coffee granules with the boiling hot water until the coffee dissolves, set aside to cool.
2 Sift the flour, baking powder, cinnamon and salt.
3 Using a stand mixer beat the softened butter and brown sugar until smooth, light and fluffy.
4 Add the vanilla extract and one egg at a time, beating until the egg is well incorporated before adding another egg.
5 Combine the cooled coffee and flour with the butter mixture, beat until just combined.
6 Fold in the chopped walnuts.
7 Transfer the cake batter into the prepared loaf tin and bake for 40-50 minutes or until an inserted skewer comes out clean. Cover the cake with a sheet of foil after 15 minutes if the top of the cake is beginning to brown quickly.
